Operation
Electrical operation
The NOVA i recloser utilizes an interface circuit located in the
mechanism housing. The electronic interface circuit controls the
opening and closing signals to the magnetic actuator.
OPEN/CLOSE contact position indicator
The OPEN/CLOSE contact position indicator consists of a red
CLOSED and a green OPEN indicator located on the bottom of the
mechanism housing (see Figure 13).
Hotstick operation (manual open, electrical
close)
The recloser may be opened manually by using a hotstick to pull
down the yellow manual OPEN handle, located on the front of the
recloser (see Figure 13). To close the recloser after a manual
opening, first, push the yellow manual open handle up. Then, using
the microprocessor control, close the recloser.
If the yellow manual OPEN handle remains in the down position, the recloser
cannot be closed electrically from the control.
